ECCS Cloud Email

The operation of ECCS Cloud Email was started in April 2016 for all faculty members and students who have ECCS account. For more information, please read the "Information on ECCS Cloud Email", and We also recommend you read "How to use ECCS Cloud Email on the use of the mail system.

ECCS Staff Email (ECCS2012 email system)

Academic and administrative staff who have the right to use ECCS are able to use ECCS Staff Email which is a system that uses a mail server installed in the university in addition to the ECCS Cloud Email.

Additionally, students who have been using ECCS before AY2015 are able to use the email system for ECCS 2012 as a transitional measure. Please save or transfer your data such as email boxes before changing over to the email system of ECCS 2016 on your own (scheduled in August 2016) For more information, please refer to "Notice on the Use of Email System Associated with the Transition to ECCS2016"

Setting Up Mailer

For those who prefer to read the ECCS emails using other mailers (mail clients) such as Apple Mail or MS Outlook, the mailer should be set up as shown the following table 1.

Configuration ItemData
Incoming Mail Server (POP) / TLS Port: 995
Incoming Mail Server (IMAP) / TLS Port: 993
Outgoing Mail / TLS Port: 465 with authentication. / Username and Password are as follows.
UsernameYour ECCS Staff Email address (ECCS
PasswordYour password for ECCS (UTokyo Account or ECCS limited Account)

Unless you have special reasons, set up your email address as IMAP. IMAP leaves the emails on the server and also organizes the emails in folders on the server. Therefore, you will be able to read the email messages from both ECCS terminals and your home computers.
